I agree with JNOVACK about verifying bad compomenst that will cause a no start condition.
I do take exception to "grounding" a plug wire to see if there is spark. You could and people often do damage any of the firing components by causing an impedence mis-match resulting in an ignition failure. I have seen a distributer cap blown completely off from grounding a plug wire.
The best and only inexpensive way is to buy a test plug from any parts store. Insert it into the plug wire ground the end with a provided clip. You can easily see the fire and the test plug has internal resistance to make the ignition sytem thing it has a plug installed.
It is an easy, clean and safe way to check for spark.
Way to verify spark.
As a note, VW engines are not close tolerance except the diesel engines so if the timig belt is bad there will be no damage. Fuel pump, external to the tank and adjoining filter are high failure VW items.
